2-Hydroxy-3,5,6-trichloropyridine is an organic compound. Its chemical properties are quite unique, let me tell you in detail.
This compound is acidic because of the hydroxyl group. Hydrogen atoms in the hydroxyl group can be partially dissociated, showing acidic properties in a suitable medium.
The chlorine atom of its substituent also affects its properties. The chlorine atom is electronegative, which can change the electron cloud density distribution of the pyridine ring by inducing effects. This change not only affects the polarity of the compound, but also plays an important role in the electrophilic substitution reaction. Pyridine rings are aromatic, but their reactivity and selectivity are different from ordinary pyridine due to the presence of chlorine atoms and hydroxyl groups.
In the nucleophilic substitution reaction, due to the activity of chlorine atoms, they can be replaced by appropriate nucleophilic reagents to form different derivatives. In this process, reaction conditions such as temperature and solvent have a great influence on the reaction rate and product selectivity.
Its stability is also affected by structure. The aromatic conjugate system of pyridine rings provides certain stability, but the introduction of chlorine atoms and hydroxyl groups, or due to steric resistance and electronic effects, affects its stability under certain conditions.
In addition, the solubility of the compound is closely related to other physical properties and its structure. In organic solvents, due to the coexistence of polar groups and aromatic structures, the solubility may exhibit specific laws.
In summary, 2-hydroxy-3,5,6-trichloropyridine is rich in chemical properties and interacts with various parts in its structure, which has important research and application value in organic synthesis and related fields.

The synthesis methods of 2-hydroxy-3,5,6-trichloropyridine are generally as follows.
First, trichloropyridine is used as the starting material and obtained by oxidation reaction. The trichloropyridine is placed in a suitable reaction vessel, added with a specific oxidant, such as potassium permanganate, potassium dichromate, etc., at a suitable temperature and reaction time, so that it undergoes oxidation reaction. During this process, the hydrogen atom at a specific position on the pyridine ring is replaced by a hydroxyl group, and then 2-hydroxy-3,5,6-trichloropyridine is obtained. However, this approach requires attention to the precise control of the amount of oxidant and the reaction conditions, otherwise it is prone to side reactions and the purity of the product will be affected.
Second, a pyridine derivative containing a specific substituent is used as the starting material and synthesized through a substitution reaction. First select a suitable pyridine derivative, which has a partial substituent at a specific position, and then introduce a chlorine atom through a halogenation reaction, and then perform a hydroxylation reaction to convert a specific position into a hydroxyl group to obtain the target product. The key to this method is the selection of the starting material and the optimization of the reaction conditions at each step to ensure the selectivity and yield of the reaction.
Third, the reaction path catalyzed by transition metals. Specific transition metal catalysts, such as palladium and copper complexes, are added to the reaction system, and suitable halogenated pyridine derivatives and hydroxyl-containing reagents are used as raw materials. Under the action of the catalyst, a coupling reaction occurs to achieve the introduction of hydroxyl groups, thereby synthesizing 2-hydroxy-3,5,6-trichloropyridine. This method requires high activity and selectivity of the catalyst, and the cost of the catalyst may be one of the factors to consider, but its advantage is that the reaction conditions are relatively mild, and the selectivity may be well controlled.

I don't have the exact price range of 2-hydroxy-3,5,6-trichloropyridine in the market. The price of this compound often changes due to many factors, such as quality, purity, purchase quantity, supply and demand status, and seller differences.
If you want to find the price, you can find chemical raw material suppliers, chemical reagent sales platforms, and ask for specific quotations. On the chemical raw material trading platform, many suppliers list prices, which can be compared, and you can know their approximate price range. However, its price is not static, the market fluctuates frequently, and sometimes the cost of raw materials increases and sometimes the demand changes, which all drive the price.
There may be past transactions, which can be used as a reference. However, the market changes rapidly, and the past price is for reference only, not the current accurate number. In order to obtain an accurate price, it is a good strategy to inquire from relevant merchants to obtain an exact price range.
